The science everyone needs to know about climate change, in 6 charts

Take a closer look at what’s driving climate change and how scientists know CO2 is involved, in a series of charts examining the evidence in different ways.

With the United Nations’ climate conference in Scotland turning a spotlight on climate change policies and the impact of global warming, it’s useful to understand what the science shows.

I’m an atmospheric scientist who has worked on global climate science and assessments for most of my career. Here are six things you should know, in charts.

What’s driving climate change

The primary focus of the negotiations is on carbon dioxide, a greenhouse gas that is released when fossil fuels – coal, oil and natural gas – are burned, as well as by forest fires, land use changes and natural sources.

The Industrial Revolution of the late 1800s started an enormous increase in the burning of fossil fuels. It powered homes, industries and opened up the planet to travel. That same century, scientists identified carbon dioxide’s potential to increase global temperatures, which at the time was considered a possible benefit to the planet. Systematic measurements started in the mid-1900s and have shown a steady increase in carbon dioxide, with the majority of it directly traceable to the combustion of fossil fuels.

Once in the atmosphere, carbon dioxide tends to stay there for a very long time. A portion of the carbon dioxide released through human activities is taken up by plants, and some is absorbed directly into the ocean, but roughly half of all carbon dioxide emitted by human activities today stays in the atmosphere — and it likely will remain there for hundreds of years, influencing the climate globally.

During the first year of the pandemic in 2020, when fewer people were driving and some industries briefly stopped, carbon dioxide emissions from fuels fell by roughly 6%. But it didn’t stop the rise in the concentration of carbon dioxide because the amount released into the atmosphere by human activities far exceeded what nature could absorb.

If civilization stopped its carbon dioxide-emitting activities today, it would still take many hundreds of years for the concentration of carbon dioxide in the atmosphere to fall enough naturally to bring the planet’s carbon cycle back into balance because of carbon dioxide’s long life in the atmosphere.

How we know greenhouse gases can change the climate

Multiple lines of scientific evidence point to the increase in greenhouse emissions over the past century and a half as a driver of long-term climate change around the world. For example:

When carbon dioxide levels have been high in the past, evidence shows temperatures have also been high. Based on Salawitch et al., 2017, updated with data to the end of 2020, CC BY
  • Long-term records from ice cores, tree rings and corals show that when carbon dioxide levels have been high, temperatures have also been high.

  • Our neighboring planets also offer evidence. Venus’ atmosphere is thick with carbon dioxide, and it is the hottest planet in our solar system as a result, even though Mercury is closer to the sun.

Temperatures are rising on every continent

The rising temperatures are evident in records from every continent and over the oceans.

The temperatures aren’t rising at the same rate everywhere, however. A variety of factors affect local temperatures, including land use that influences how much solar energy is absorbed or reflected, local heating sources like urban heat islands, and pollution.

The Arctic, for example, is warming about three times faster than the global average in part because as the planet warms, snow and ice melt makes the surface more likely to absorb, rather than reflect, the sun’s radiation. Snow cover and sea ice recede even more rapidly as a result.

What climate change is doing to the planet

Earth’s climate system is interconnected and complex, and even small temperature changes can have large impacts – for instance, with snow cover and sea levels.

Changes are already happening. Studies show that rising temperatures are already affecting precipitation, glaciers, weather patterns, tropical cyclone activity and severe storms. A number of studies show that the increases in frequency, severity and duration of heat waves, for example, affect ecosystems, human lives, commerce and agriculture.

Historical records of ocean water level have shown mostly consistent increases over the past 150 years as glacier ice melts and rising temperatures expand ocean water, with some local deviations due to sinking or rising land.

While extreme events are often due to complex sets of causes, some are exacerbated by climate change. Just as coastal flooding can be made worse by rising ocean levels, heat waves are more damaging with higher baseline temperatures.

Climate scientists work hard to estimate future changes as a result of increased carbon dioxide and other expected changes, such as world population. It’s clear that temperatures will increase and precipitation will change. The exact magnitude of change depends on many interacting factors.

A few reasons for hope

On a hopeful note, scientific research is improving our understanding of climate and the complex Earth system, identifying the most vulnerable areas and guiding efforts to reduce the drivers of climate change. Work on renewable energy and alternative energy sources, as well as ways to capture carbon from industries or from the air, are producing more options for a better prepared society.

At the same time, people are learning about how they can reduce their own impact, with the growing understanding that a globally coordinated effort is required to have a significant impact. Electric vehicles, as well as solar and wind power, are growing at previously unthinkable rates. More people are showing a willingness to adopt new strategies to use energy more efficiently, consume more sustainably and choose renewable energy.

Scientists increasingly recognize that shifting away from fossil fuels has additional benefits, including improved air quality for human health and ecosystems.

Digital Currency And Gold As Speculative Warnings

Published

on

Over the last few years, digital currencies and gold have become decent barometers of speculative investor appetite. Such isn’t surprising given the evolution of the market into a “casino” following the pandemic, where retail traders have increased their speculative appetites.

“Such is unsurprising, given that retail investors often fall victim to the psychological behavior of the “fear of missing out.” The chart below shows the “dumb money index” versus the S&P 500. Once again, retail investors are very long equities relative to the institutional players ascribed to being the “smart money.””

“The difference between “smart” and “dumb money” investors shows that, more often than not, the “dumb money” invests near market tops and sells near market bottoms.”

Net Smart Dumb Money vs Market

That enthusiasm has increased sharply since last November as stocks surged in hopes that the Federal Reserve would cut interest rates. As noted by Sentiment Trader:

“Over the past 18 weeks, the straight-up rally has moved us to an interesting juncture in the Sentiment Cycle. For the past few weeks, the S&P 500 has demonstrated a high positive correlation to the ‘Enthusiasm’ part of the cycle and a highly negative correlation to the ‘Panic’ phase.”

Investor Enthusiasm

That frenzy to chase the markets, driven by the psychological bias of the “fear of missing out,” has permeated the entirety of the market. As noted in This Is Nuts:”

“Since then, the entire market has surged higher following last week’s earnings report from Nvidia (NVDA). The reason I say “this is nuts” is the assumption that all companies were going to grow earnings and revenue at Nvidia’s rate. There is little doubt about Nvidia’s earnings and revenue growth rates. However, to maintain that growth pace indefinitely, particularly at 32x price-to-sales, means others like AMD and Intel must lose market share.”

Nvidia Price To Sales

Of course, it is not just a speculative frenzy in the markets for stocks, specifically anything related to “artificial intelligence,” but that exuberance has spilled over into gold and cryptocurrencies.

Birds Of A Feather

There are a couple of ways to measure exuberance in the assets. While sentiment measures examine the broad market, technical indicators can reflect exuberance on individual asset levels. However, before we get to our charts, we need a brief explanation of statistics, specifically, standard deviation.

As I discussed in “Revisiting Bob Farrell’s 10 Investing Rules”:

“Like a rubber band that has been stretched too far – it must be relaxed in order to be stretched again. This is exactly the same for stock prices that are anchored to their moving averages. Trends that get overextended in one direction, or another, always return to their long-term average. Even during a strong uptrend or strong downtrend, prices often move back (revert) to a long-term moving average.”

The idea of “stretching the rubber band” can be measured in several ways, but I will limit our discussion this week to Standard Deviation and measuring deviation with “Bollinger Bands.”

“Standard Deviation” is defined as:

“A measure of the dispersion of a set of data from its mean. The more spread apart the data, the higher the deviation. Standard deviation is calculated as the square root of the variance.”

In plain English, this means that the further away from the average that an event occurs, the more unlikely it becomes. As shown below, out of 1000 occurrences, only three will fall outside the area of 3 standard deviations. 95.4% of the time, events will occur within two standard deviations.

Standard Deviation Chart

A second measure of “exuberance” is “relative strength.”

“In technical analysis, the relative strength index (RSI) is a momentum indicator that measures the magnitude of recent price changes to evaluate overbought or oversold conditions in the price of a stock or other asset. The RSI is displayed as an oscillator (a line graph that moves between two extremes) and can read from 0 to 100.

Traditional interpretation and usage of the RSI are that values of 70 or above indicate that a security is becoming overbought or overvalued and may be primed for a trend reversal or corrective pullback in price. An RSI reading of 30 or below indicates an oversold or undervalued condition.” – Investopedia

With those two measures, let’s look at Nvidia (NVDA), the poster child of speculative momentum trading in the markets. Nvidia trades more than 3 standard deviations above its moving average, and its RSI is 81. The last time this occurred was in July of 2023 when Nvidia consolidated and corrected prices through November.

NVDA chart vs Bollinger Bands

Interestingly, gold also trades well into 3 standard deviation territory with an RSI reading of 75. Given that gold is supposed to be a “safe haven” or “risk off” asset, it is instead getting swept up in the current market exuberance.

Gold vs Bollinger Bands

The same is seen with digital currencies. Given the recent approval of spot, Bitcoin exchange-traded funds (ETFs), the panic bid to buy Bitcoin has pushed the price well into 3 standard deviation territory with an RSI of 73.

Bitcoin vs Bollinger Bands

In other words, the stock market frenzy to “buy anything that is going up” has spread from just a handful of stocks related to artificial intelligence to gold and digital currencies.

It’s All Relative

We can see the correlation between stock market exuberance and gold and digital currency, which has risen since 2015 but accelerated following the post-pandemic, stimulus-fueled market frenzy. Since the market, gold and cryptocurrencies, or Bitcoin for our purposes, have disparate prices, we have rebased the performance to 100 in 2015.

Gold was supposed to be an inflation hedge. Yet, in 2022, gold prices fell as the market declined and inflation surged to 9%. However, as inflation has fallen and the stock market surged, so has gold. Notably, since 2015, gold and the market have moved in a more correlated pattern, which has reduced the hedging effect of gold in portfolios. In other words, during the subsequent market decline, gold will likely track stocks lower, failing to provide its “wealth preservation” status for investors.

SP500 vs Gold

The same goes for cryptocurrencies. Bitcoin is substantially more volatile than gold and tends to ebb and flow with the overall market. As sentiment surges in the S&P 500, Bitcoin and other cryptocurrencies follow suit as speculative appetites increase. Unfortunately, for individuals once again piling into Bitcoin to chase rising prices, if, or when, the market corrects, the decline in cryptocurrencies will likely substantially outpace the decline in market-based equities. This is particularly the case as Wall Street can now short the spot-Bitcoin ETFs, creating additional selling pressure on Bitcoin.

SP500 vs Bitcoin

Just for added measure, here is Bitcoin versus gold.

Gold vs Bitcoin

Not A Recommendation

There are many narratives surrounding the markets, digital currency, and gold. However, in today’s market, more than in previous years, all assets are getting swept up into the investor-feeding frenzy.

Sure, this time could be different. I am only making an observation and not an investment recommendation.

However, from a portfolio management perspective, it will likely pay to remain attentive to the correlated risk between asset classes. If some event causes a reversal in bullish exuberance, cash and bonds may be the only place to hide.

Four Years Ago This Week, Freedom Was Torched

Four Years Ago This Week, Freedom Was Torched

Authored by Jeffrey Tucker via The Brownstone Institute,

"Beware the Ides of March,” Shakespeare quotes the soothsayer’s warning Julius Caesar about what turned out to be an impending assassination on March 15. The death of American liberty happened around the same time four years ago, when the orders went out from all levels of government to close all indoor and outdoor venues where people gather. 

It was not quite a law and it was never voted on by anyone. Seemingly out of nowhere, people who the public had largely ignored, the public health bureaucrats, all united to tell the executives in charge – mayors, governors, and the president – that the only way to deal with a respiratory virus was to scrap freedom and the Bill of Rights. 

And they did, not only in the US but all over the world. 

The forced closures in the US began on March 6 when the mayor of Austin, Texas, announced the shutdown of the technology and arts festival South by Southwest. Hundreds of thousands of contracts, of attendees and vendors, were instantly scrapped. The mayor said he was acting on the advice of his health experts and they in turn pointed to the CDC, which in turn pointed to the World Health Organization, which in turn pointed to member states and so on. 

There was no record of Covid in Austin, Texas, that day but they were sure they were doing their part to stop the spread. It was the first deployment of the “Zero Covid” strategy that became, for a time, official US policy, just as in China. 

It was never clear precisely who to blame or who would take responsibility, legal or otherwise. 

This Friday evening press conference in Austin was just the beginning. By the next Thursday evening, the lockdown mania reached a full crescendo. Donald Trump went on nationwide television to announce that everything was under control but that he was stopping all travel in and out of US borders, from Europe, the UK, Australia, and New Zealand. American citizens would need to return by Monday or be stuck. 

Americans abroad panicked while spending on tickets home and crowded into international airports with waits up to 8 hours standing shoulder to shoulder. It was the first clear sign: there would be no consistency in the deployment of these edicts. 

There is no historical record of any American president ever issuing global travel restrictions like this without a declaration of war. Until then, and since the age of travel began, every American had taken it for granted that he could buy a ticket and board a plane. That was no longer possible. Very quickly it became even difficult to travel state to state, as most states eventually implemented a two-week quarantine rule. 

The next day, Friday March 13, Broadway closed and New York City began to empty out as any residents who could went to summer homes or out of state. 

On that day, the Trump administration declared the national emergency by invoking the Stafford Act which triggers new powers and resources to the Federal Emergency Management Administration. 

In addition, the Department of Health and Human Services issued a classified document, only to be released to the public months later. The document initiated the lockdowns. It still does not exist on any government website.

The White House Coronavirus Response Task Force, led by the Vice President, will coordinate a whole-of-government approach, including governors, state and local officials, and members of Congress, to develop the best options for the safety, well-being, and health of the American people. HHS is the LFA [Lead Federal Agency] for coordinating the federal response to COVID-19.

Closures were guaranteed:

Recommend significantly limiting public gatherings and cancellation of almost all sporting events, performances, and public and private meetings that cannot be convened by phone. Consider school closures. Issue widespread ‘stay at home’ directives for public and private organizations, with nearly 100% telework for some, although critical public services and infrastructure may need to retain skeleton crews. Law enforcement could shift to focus more on crime prevention, as routine monitoring of storefronts could be important.

In this vision of turnkey totalitarian control of society, the vaccine was pre-approved: “Partner with pharmaceutical industry to produce anti-virals and vaccine.”

The National Security Council was put in charge of policy making. The CDC was just the marketing operation. That’s why it felt like martial law. Without using those words, that’s what was being declared. It even urged information management, with censorship strongly implied.

The timing here is fascinating. This document came out on a Friday. But according to every autobiographical account – from Mike Pence and Scott Gottlieb to Deborah Birx and Jared Kushner – the gathered team did not meet with Trump himself until the weekend of the 14th and 15th, Saturday and Sunday. 

According to their account, this was his first real encounter with the urge that he lock down the whole country. He reluctantly agreed to 15 days to flatten the curve. He announced this on Monday the 16th with the famous line: “All public and private venues where people gather should be closed.”

This makes no sense. The decision had already been made and all enabling documents were already in circulation. 

There are only two possibilities. 

One: the Department of Homeland Security issued this March 13 HHS document without Trump’s knowledge or authority. That seems unlikely. 

Two: Kushner, Birx, Pence, and Gottlieb are lying. They decided on a story and they are sticking to it. 

Trump himself has never explained the timeline or precisely when he decided to greenlight the lockdowns. To this day, he avoids the issue beyond his constant claim that he doesn’t get enough credit for his handling of the pandemic.

With Nixon, the famous question was always what did he know and when did he know it? When it comes to Trump and insofar as concerns Covid lockdowns – unlike the fake allegations of collusion with Russia – we have no investigations. To this day, no one in the corporate media seems even slightly interested in why, how, or when human rights got abolished by bureaucratic edict. 

As part of the lockdowns, the Cybersecurity and Infrastructure Security Agency, which was and is part of the Department of Homeland Security, as set up in 2018, broke the entire American labor force into essential and nonessential.

They also set up and enforced censorship protocols, which is why it seemed like so few objected. In addition, CISA was tasked with overseeing mail-in ballots. 

Only 8 days into the 15, Trump announced that he wanted to open the country by Easter, which was on April 12. His announcement on March 24 was treated as outrageous and irresponsible by the national press but keep in mind: Easter would already take us beyond the initial two-week lockdown. What seemed to be an opening was an extension of closing. 

This announcement by Trump encouraged Birx and Fauci to ask for an additional 30 days of lockdown, which Trump granted. Even on April 23, Trump told Georgia and Florida, which had made noises about reopening, that “It’s too soon.” He publicly fought with the governor of Georgia, who was first to open his state. 

Before the 15 days was over, Congress passed and the president signed the 880-page CARES Act, which authorized the distribution of $2 trillion to states, businesses, and individuals, thus guaranteeing that lockdowns would continue for the duration. 

There was never a stated exit plan beyond Birx’s public statements that she wanted zero cases of Covid in the country. That was never going to happen. It is very likely that the virus had already been circulating in the US and Canada from October 2019. A famous seroprevalence study by Jay Bhattacharya came out in May 2020 discerning that infections and immunity were already widespread in the California county they examined. 

What that implied was two crucial points: there was zero hope for the Zero Covid mission and this pandemic would end as they all did, through endemicity via exposure, not from a vaccine as such. That was certainly not the message that was being broadcast from Washington. The growing sense at the time was that we all had to sit tight and just wait for the inoculation on which pharmaceutical companies were working. 

By summer 2020, you recall what happened. A restless generation of kids fed up with this stay-at-home nonsense seized on the opportunity to protest racial injustice in the killing of George Floyd. Public health officials approved of these gatherings – unlike protests against lockdowns – on grounds that racism was a virus even more serious than Covid. Some of these protests got out of hand and became violent and destructive. 

Meanwhile, substance abuse rage – the liquor and weed stores never closed – and immune systems were being degraded by lack of normal exposure, exactly as the Bakersfield doctors had predicted. Millions of small businesses had closed. The learning losses from school closures were mounting, as it turned out that Zoom school was near worthless. 

It was about this time that Trump seemed to figure out – thanks to the wise council of Dr. Scott Atlas – that he had been played and started urging states to reopen. But it was strange: he seemed to be less in the position of being a president in charge and more of a public pundit, Tweeting out his wishes until his account was banned. He was unable to put the worms back in the can that he had approved opening. 

By that time, and by all accounts, Trump was convinced that the whole effort was a mistake, that he had been trolled into wrecking the country he promised to make great. It was too late. Mail-in ballots had been widely approved, the country was in shambles, the media and public health bureaucrats were ruling the airwaves, and his final months of the campaign failed even to come to grips with the reality on the ground. 

At the time, many people had predicted that once Biden took office and the vaccine was released, Covid would be declared to have been beaten. But that didn’t happen and mainly for one reason: resistance to the vaccine was more intense than anyone had predicted. The Biden administration attempted to impose mandates on the entire US workforce. Thanks to a Supreme Court ruling, that effort was thwarted but not before HR departments around the country had already implemented them. 

As the months rolled on – and four major cities closed all public accommodations to the unvaccinated, who were being demonized for prolonging the pandemic – it became clear that the vaccine could not and would not stop infection or transmission, which means that this shot could not be classified as a public health benefit. Even as a private benefit, the evidence was mixed. Any protection it provided was short-lived and reports of vaccine injury began to mount. Even now, we cannot gain full clarity on the scale of the problem because essential data and documentation remains classified. 

After four years, we find ourselves in a strange position. We still do not know precisely what unfolded in mid-March 2020: who made what decisions, when, and why. There has been no serious attempt at any high level to provide a clear accounting much less assign blame. 

Not even Tucker Carlson, who reportedly played a crucial role in getting Trump to panic over the virus, will tell us the source of his own information or what his source told him. There have been a series of valuable hearings in the House and Senate but they have received little to no press attention, and none have focus on the lockdown orders themselves. 

The prevailing attitude in public life is just to forget the whole thing. And yet we live now in a country very different from the one we inhabited five years ago. Our media is captured. Social media is widely censored in violation of the First Amendment, a problem being taken up by the Supreme Court this month with no certainty of the outcome. The administrative state that seized control has not given up power. Crime has been normalized. Art and music institutions are on the rocks. Public trust in all official institutions is at rock bottom. We don’t even know if we can trust the elections anymore. 

In the early days of lockdown, Henry Kissinger warned that if the mitigation plan does not go well, the world will find itself set “on fire.” He died in 2023. Meanwhile, the world is indeed on fire. The essential struggle in every country on earth today concerns the battle between the authority and power of permanent administration apparatus of the state – the very one that took total control in lockdowns – and the enlightenment ideal of a government that is responsible to the will of the people and the moral demand for freedom and rights. 

How this struggle turns out is the essential story of our times.

CDC Warns Thousands Of Children Sent To ER After Taking Common Sleep Aid

CDC Warns Thousands Of Children Sent To ER After Taking Common Sleep Aid

Authored by Jack Phillips via The Epoch Times (emphasis ours),

A U.S. Centers for Disease Control (CDC) paper released Thursday found that thousands of young children have been taken to the emergency room over the past several years after taking the very common sleep-aid supplement melatonin.

The agency said that melatonin, which can come in gummies that are meant for adults, was implicated in about 7 percent of all emergency room visits for young children and infants “for unsupervised medication ingestions,” adding that many incidents were linked to the ingestion of gummy formulations that were flavored. Those incidents occurred between the years 2019 and 2022.

Melatonin is a hormone produced by the human body to regulate its sleep cycle. Supplements, which are sold in a number of different formulas, are generally taken before falling asleep and are popular among people suffering from insomnia, jet lag, chronic pain, or other problems.

The supplement isn’t regulated by the U.S. Food and Drug Administration and does not require child-resistant packaging. However, a number of supplement companies include caps or lids that are difficult for children to open.

The CDC report said that a significant number of melatonin-ingestion cases among young children were due to the children opening bottles that had not been properly closed or were within their reach. Thursday’s report, the agency said, “highlights the importance of educating parents and other caregivers about keeping all medications and supplements (including gummies) out of children’s reach and sight,” including melatonin.

The approximately 11,000 emergency department visits for unsupervised melatonin ingestions by infants and young children during 2019–2022 highlight the importance of educating parents and other caregivers about keeping all medications and supplements (including gummies) out of children’s reach and sight.

The CDC notes that melatonin use among Americans has increased five-fold over the past 25 years or so. That has coincided with a 530 percent increase in poison center calls for melatonin exposures to children between 2012 and 2021, it said, as well as a 420 percent increase in emergency visits for unsupervised melatonin ingestion by young children or infants between 2009 and 2020.

Some health officials advise that children under the age of 3 should avoid taking melatonin unless a doctor says otherwise. Side effects include drowsiness, headaches, agitation, dizziness, and bed wetting.

Other symptoms of too much melatonin include nausea, diarrhea, joint pain, anxiety, and irritability. The supplement can also impact blood pressure.

However, there is no established threshold for a melatonin overdose, officials have said. Most adult melatonin supplements contain a maximum of 10 milligrams of melatonin per serving, and some contain less.

Many people can tolerate even relatively large doses of melatonin without significant harm, officials say. But there is no antidote for an overdose. In cases of a child accidentally ingesting melatonin, doctors often ask a reliable adult to monitor them at home.

Dr. Cora Collette Breuner, with the Seattle Children’s Hospital at the University of Washington, told CNN that parents should speak with a doctor before giving their children the supplement.

“I also tell families, this is not something your child should take forever. Nobody knows what the long-term effects of taking this is on your child’s growth and development,” she told the outlet. “Taking away blue-light-emitting smartphones, tablets, laptops, and television at least two hours before bed will keep melatonin production humming along, as will reading or listening to bedtime stories in a softly lit room, taking a warm bath, or doing light stretches.”

In 2022, researchers found that in 2021, U.S. poison control centers received more than 52,000 calls about children consuming worrisome amounts of the dietary supplement. That’s a six-fold increase from about a decade earlier. Most such calls are about young children who accidentally got into bottles of melatonin, some of which come in the form of gummies for kids, the report said.

Dr. Karima Lelak, an emergency physician at Children’s Hospital of Michigan and the lead author of the study published in 2022 by the CDC, found that in about 83 percent of those calls, the children did not show any symptoms.

However, other children had vomiting, altered breathing, or other symptoms. Over the 10 years studied, more than 4,000 children were hospitalized, five were put on machines to help them breathe, and two children under the age of two died. Most of the hospitalized children were teenagers, and many of those ingestions were thought to be suicide attempts.

Those researchers also suggested that COVID-19 lockdowns and virtual learning forced more children to be at home all day, meaning there were more opportunities for kids to access melatonin. Also, those restrictions may have caused sleep-disrupting stress and anxiety, leading more families to consider melatonin, they suggested.
